Given how greatly an XL engine increases weight competence but decreases largely survivability I was wonder the views of some group on it and if they are likely to use it.

Personally I will make use mainly of ferro and endo to achieve similar results except for mechs which I feel are improbable to survive well in direct combat besides like scouts or long range bear mechs. This I think will also assist with cost as an XL engine is 4 times as classy as a normal fusion engine.
